Validity refers to how accurate an instrument measures what it is supposed to measure, or in short how accurate your research study is.
there are internal validity (measurement and test) and external validity (ability to generalize the target population findings)
types of internal validity and how to improve it in research studies
Reliability
refers to the consistency of a test
internal reliability : tests consistency within tests
methods to check: split-half method
assessing by spliting the whole test into half and check
external reliability : extent to which the result changes from test to test
test re-test method: checking over and over again for the consistency
inter-rater: consistency rate given by different raters for the same behavior
trustworthiness
